OBJECTIVETo systematically review the clinical efficacy of acupuncture on the patients with low back pain (LBP).

METHODSRandomized controlled trials (RCTs) about pure acupuncture therapy versus other treatments in treating LBP were electronically searched in PubMed, CBM, EMbase, The Cochrane Library, CNKI, VIP and Wanfang Data from January 2004 to May 2014. The observed index on the results were the changed scores of VAS, ODI, JOA and RMDQ. Two reviewers independently screened the literatures according to the inclusion and exclusion criteria, as well as the extracted data, and assessed the methodological quality. The results of Meta-analysis was conducted by RevMan 5.2 software.

RESULTSTen RCTs involved 751 patients were finally included. The results of Meta-analysis indicated that the role of pure acupuncture group in improving the VAS score was better than that of the control group, and the combined effect size was RR = -.32, 95% CI (-1.41, -1.22); Z=27.28, P<0.00001; the role of pure acupuncture group in improving the ODI score was better than that of the control group, and the combined effect size was RR = -5.07, 95% CI (-7.50, -2.65); Z=4.10, P<0.0001; the role of pure acupuncture group on improved JOA score was better than that of the control group and the combined effect size was RR=2.83, 95% CI (2.02, 3.63), Z=6.90, P<0.00001. The role of pure acupuncture group in improving the RMDQ score was better than that of the control group, and the combined effect size was RR = -2.80, 95% CI (-3.49, -2.11), Z=7.95, P<0.00001.

CONCLUSIONThe result of meta-analysis demonstrates that pure acupuncture may have a favorable effect on self-reported pain and functional limitations in LBP patients.

Objective:To optimize the extraction technology of Fufang Jinsha Lidan granule. Methods:According to the properties of traditional Chinese medicines in the formula, orthogonal experiments were used to optimize the extraction process of Fufang Jinsha Li-dan granule. The volume of water, boiling time and boiling frequency were used as the three influencing factors with three different lev-els in the orthogonal experiments. Moreover, the content of paeoniflorin and the yield of extract were chosen as the evaluation indices. The orthogonal experiments were carried out according to the L9 (34 ) orthogonal table. Results:The optimal extraction process of Fu-fang Jinsha Lidan granule was as follows:boiled twice, and one hour per time with 12-fold amount of water ( soaked for 30 min with 14-fold amount of water for the first extraction process) . Conclusion:The extraction process has such properties as high extraction rate, stability, simple operation, high yield of extract and controllable quality, which is worthy of wide application.

Objective To investigate the fuction of tumor necrosis factor alpha(TNF-?),interleukin-1 beta(IL-1?) and interleukin-6(IL-6) in children with intracranial infection.Methods TNF-?,IL-1? and IL-6 levels of serum and cerebrospinal fluid(CSF) were determined in the purulent meningitis group(25 cases),tuberculous meningitis group(17 cases),viral meningitis group(30 cases)and control group(20 cases)by enzyme-linked immunosorbent assay(ELISA).Results The levels of TNF-?,IL-1? and IL-6 obviously increased in CSF compared with that in the serum (Pa

Background Q-value is used to express the asphricity of the anterior corneal surface.As a optical surface,the optial morphology of cornea is composed of a series of tangential sections that cut-off through the optical axial.Therefore,tangential section could represent the true optical morphology of the corneal surface,and Q-value calculation by tangential radius can better represent the asphericity.Objective This study was to calculate Q-value of meridian section of the anterior corneal surface by tangential radius of the tangential topography and analyze the corneal asphericity in horizontal interval.Methods Ninety right eyes of 90 myopia subjects aged 16-30years and with mean spherical equivalent of (-5.45 ± 2.75) D received corneal topography examination using Orbscan Ⅱ system.The subjects were assigned to low myopia group,moderate myopia group and high myopia group based on their diopter and 30 eyes for each group.The tangential curvatures on meridian section at a 0.1 mm interval from apex to periphery of the anterior surface were accepted and the Q value of the semimeridian section was calculated by linear regression mathematical formulas of the tangential radius.Mydriatic optometry,intraocular pressure,keratometer and fundus examinations were performed on the subjects.Written informed consent was obtained from each subject before any medical examination.Results The coefficients of determination in all the semimeridians were over 0.5.The average calculated Q-values in the nasal and temporal horizontal interval were -0.32±0.11 and-0.30±0.12,with a significant difference between them (t =2.009,P＜0.05).The vertex radius of curvature was (7.78±0.27)mm and (7.72±0.25)mm respectively in the nasal and temporal horizontal interval,showing a significant difference(t=-1.016,P＞0.05).No significant difference was seen in Q values of both nasal and temporal areas among three myopic groups (nasal:F =0.192,P =0.825 ; temporal:F =0.912,P =0.406).The average Q value of the nasal and temporal principal meridian was-0.33±0.14 and-0.30±0.13 respectively,and the r0 was 7.76±0.30 and 7.74±0.24 respectively.A weak positive correlation was found between r0 and mean Q value of nasal meridian (r=0.320,P＜0.05),but no significant correlation was found between r0 and mean Q-value of temporal meridian (r=0.104,P＞0.05).No significant differenees were seen in the Q values between nasal meridian and nasal zone (t=0.349,P＞0.05) as well as between temporal meridian and temporal zone(t=-0.373,P＞0.05).Conclusions The study analyzes the calculated Q-value of the semimeridian section in borizontal area with myopia by linear regression mathematical formulas of tangential radius on tangential topography.The anterior surface of the cornea is proved to be prolate ellipse in shape in the subjects with myopia.

The effects of ultrafine grinding on the dissolution rates of the effective components in Sanjie Zhentong capsule (SZC) were studied in this experiment. Fine and ultrafine powder of SZC intermediates were made by ordinary grinding and ultrafine grinding technology, and then granulated by wet granulation. SZC were prepared by fine powder, ultrafine powder and ultrafine granules, respectively. With resveratrol and loureirin B as investigated indexes, dissolution rates of the four intermediates in SZC were determined by cup method and HPLC. The dissolution rates of resveratrol in SZC prepared by fine powder, ultrafine powder and ultrafine granules were 26.11%, 63.27%, 67.49%, respectively; and the dissolution rates of loureirin B were 7.160%, 20.29%, 23.05%, respectively. The dissolution rate of resveratrol and loureirin B in SZC prepared by ultrafine granules was the best. D90 size of ultrafine grinding was 13.221 μm and could improve the dissolution rates of resveratrol and loureirin B in SZC.

An average follow-up of 5.8 years was made in 154 cases(91.1%).Local recurrence was 5.8%.Hepatic metastasis was 13.7%.The five year survival rate was 66.9%. Conclusion This anal-sphincter preserving procedure while fulfilling radical resection for middle-lower rectal carcinoma is both safe and feasible alternative approach.

OBJECTIVETo investigate the modification of GSTM1, GSTT1 and GSTP1 gene polymorphisms on urinary 1-hydroxypyrene (1-OHP) excretions in workers under different exposure levels.

METHODSFour hundred and forty-seven occupationally exposed workers from two coking plants and 220 control workers from a wire rod plant were genotyped to analyze the modification of GSTM1, GSTT1 and GSTP1 gene polymorphisms on urinary 1-OHP excretions.

RESULTSThe urinary 1-OHP concentration in exposed group was much higher than that in control group (4.61 vs 0.34 µmol/mol Cr, P < 0.05). Occupational exposure levels and cigarette smoking were of the dominating factors affecting 1-OHP excretions in urine. After controlling potential confounders, decreased excretion of urinary 1-OHP was associated with GSTP1 I105V AG + GG genotype in coke oven workers (single-gene model, P = 0.012; multi-gene model, P = 0.011) and with GSTT1 null type in the analysis including all subjects (P = 0.055 in both single-gene and multi-gene models). GSTT1 and GSTP1 were interacted on the urinary concentrations of 1-OHP.

CONCLUSIONUrinary 1-OHP concentrations can be modified by GSTM1, GSTT1 and GSTP1 gene polymorphisms, indicating that these genes are involved in the metabolism of polycyclic aromatic hydrocarbons.
